The Use of Bioimpedance Analysis to Evaluate Lymphedema

Annals of Plastic Surgery, 2007
Lymphedema, a chronic disfiguring condition resulting from lymphatic dysfunction or disruption, can be difficult to accurately diagnose and manage. Of particular challenge is identifying the presence of clinically significant limb swelling through simple and noninvasive methods.

Simulation of Bioimpedance Analysis in MATLAB

Biomedical Engineering, 2013
Technology for simulation of bioimpedance analysis is presented using mathematical and physical models of Simulink MATLAB software. The resulting virtual bioimpedance model allows dynamic and basic bioimpedance components to be simulated, thereby providing adequate models for a biological object, as well as a monitoring tract.

Modeling and Analysis of Bioimpedance Measurements

2014
In this work we presented the technology for high-resolution efficient numerical modeling of bioimpedance measurements. This technology includes 3D image segmentation, adaptive unstructured tetrahedral mesh generation, finite-element discretization, and the analysis of simulation data.

Localized bioimpedance analysis in the evaluation of neuromuscular disease

Muscle & Nerve, 2002
AbstractLocalized bioimpedance analysis is a novel, noninvasive technique with potential application to neuromuscular disease. In this procedure, high‐frequency alternating current is passed through muscle, and parameters related to the consequent voltage pattern are evaluated.

Clinical utility of bioimpedance analysis in liver cirrhosis

Journal of Hepato-Biliary-Pancreatic Sciences, 2017
AbstractBackgroundThe objective of the present study was to examine the impact of muscle mass depletion (MMD) as determined by data in bioimpedance analysis (BIA) in liver cirrhosis (LC) patients (n = 382, 204 in male and 178 in female) on survival and to validate the utility of cutoff values in BIA recommended from current recommendations ...

Bioimpedance Analysis (BIA) in Hemodialysis: Technical Aspects

The International Journal of Artificial Organs, 1995
Phase-sensitive impedance analysis in association with anthropometric parameters provides adequate body composition estimates in nephropathic subjects, with complex three-compartment modelling as a reference. Extracellular fluid shifts can be detected during ultrafiltration by phase sensitive impedance analyzers.

Bioimpedance For Analysis of Body Composition in Sports

Journal of Medical Device Technology, 2023
Phase angle (PhA), a bioelectrical impedance analysis (BIA) parameter, has proven to be a proxy of body cell mass in athletes, but very few data are available on its segmental evaluation (upper and lower limbs). Therefore, the aim of this study is to assess whether whole-body and segmental PhA varied among elite male athletes of different sports and ...

Bioimpedance analysis: Should it be used in morbid obesity?

American Journal of Human Biology, 2011
AbstractObjectives:Questions about reliability of bioimpedance analysis (BIA) in morbidly obese subjects have curtailed its use in this setting, but metabolic implications might reignite the debate. In a prospective study, it was aimed to analyze anthropometric and clinical associations.Methods:Bariatric candidates (n = 94) with or without metabolic ...

Fourier Analysis of Human Finger Bioimpedance Variances

Bulletin of Experimental Biology and Medicine, 2010
Fourier analysis was employed to determine the amplitudes of spectrum components of small variations of electrical resistance (bioimpedance) in human finger recorded using an original hardware-software complex. It revealed periodic bioimpedance oscillations at the frequencies of heartbeats, respiration, and Mayer wave (0.1 Hz).
